Zend Framework 1.6.2 Manual

There are two methods, which provide saving changes to the PDF document. These are Zend_Pdf::save() and Zend_Pdf::render() methods.

Zend_Pdf::save($filename, $updateOnly = false) saves the PDF document to a file. If $updateOnly is true, then only the new PDF file segment is appended to a file. Otherwise, the file is overwritten.

Zend_Pdf::render($newSegmentOnly = false) returns the PDF document as a string. If $newSegmentOnly is true, then only the new PDF file segment is returned.

save($fileName, true);
// Save document as a new file
$pdf->save($newFileName);

// Return PDF document as a string.
$pdfString = $pdf->render();
